Natrolite prisms growing from the base of bladed thomsonite. At first, I thought that the natrolite terminations were coated in hyalite opal, with that typical blobby look. But when you look down on the terminations, they are stock standard natrolite terminations. So it seems that the natrolite crystals have increased in size towards the tops. Ex Jo Price Collection.
